2015-10-09qdev: Protect device-list-properties against broken devicesMarkus Armbruster1-0/+13
Several devices don't survive object_unref(object_new(T)): they crash or hang during cleanup, or they leave dangling pointers behind. This breaks at least device-list-properties, because qmp_device_list_properties() needs to create a device to find its properties. Broken in commit f4eb32b "qmp: show QOM properties in device-list-properties", v2.1. Example reproducer: $ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio {"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}} { "execute": "qmp_capabilities" } {"return": {}} { "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } } qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed. Aborted (core dumped) [Exit 134 (SIGABRT)] Unfortunately, I can't fix the problems in these devices right now. Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet to mark them: * Hang during cleanup (didn't debug, so I can't say why): "realview_pci", "versatile_pci". * Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic", "fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such CPUs * Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu", "host-powerpc64-cpu", "host-embedded-powerpc-cpu", "host-powerpc-cpu" (the powerpc ones can't currently reach the assertion, because the CPUs are only registered when KVM is enabled, but the assertion is arguably in the wrong place all the same) Make qmp_device_list_properties() fail cleanly when the device is so marked. This improves device-list-properties from "crashes, hangs or leaves dangling pointers behind" to "fails". Not a complete fix, just a better-than-nothing work-around. In the above reproducer, device-list-properties now fails with "Can't list properties of device 'pxa2xx-pcmcia'". This also protects -device FOO,help, which uses the same machinery since commit ef52358 "qdev-monitor: include QOM properties in -device FOO, help output", v2.2.

2015-10-05memory: Allow replay of IOMMU mapping notificationsDavid Gibson1-0/+13
When we have guest visible IOMMUs, we allow notifiers to be registered which will be informed of all changes to IOMMU mappings. This is used by vfio to keep the host IOMMU mappings in sync with guest IOMMU mappings. However, unlike with a memory region listener, an iommu notifier won't be told about any mappings which already exist in the (guest) IOMMU at the time it is registered. This can cause problems if hotplugging a VFIO device onto a guest bus which had existing guest IOMMU mappings, but didn't previously have an VFIO devices (and hence no host IOMMU mappings). This adds a memory_region_iommu_replay() function to handle this case. It replays any existing mappings in an IOMMU memory region to a specified notifier. Because the IOMMU memory region doesn't internally remember the granularity of the guest IOMMU it has a small hack where the caller must specify a granularity at which to replay mappings. If there are finer mappings in the guest IOMMU these will be reported in the iotlb structures passed to the notifier which it must handle (probably causing it to flag an error). This isn't new - the VFIO iommu notifier must already handle notifications about guest IOMMU mappings too short for it to represent in the host IOMMU.

2015-10-05vfio: Check guest IOVA ranges against host IOMMU capabilitiesDavid Gibson1-0/+6
The current vfio core code assumes that the host IOMMU is capable of mapping any IOVA the guest wants to use to where we need. However, real IOMMUs generally only support translating a certain range of IOVAs (the "DMA window") not a full 64-bit address space. The common x86 IOMMUs support a wide enough range that guests are very unlikely to go beyond it in practice, however the IOMMU used on IBM Power machines - in the default configuration - supports only a much more limited IOVA range, usually 0..2GiB. If the guest attempts to set up an IOVA range that the host IOMMU can't map, qemu won't report an error until it actually attempts to map a bad IOVA. If guest RAM is being mapped directly into the IOMMU (i.e. no guest visible IOMMU) then this will show up very quickly. If there is a guest visible IOMMU, however, the problem might not show up until much later when the guest actually attempt to DMA with an IOVA the host can't handle. This patch adds a test so that we will detect earlier if the guest is attempting to use IOVA ranges that the host IOMMU won't be able to deal with. For now, we assume that "Type1" (x86) IOMMUs can support any IOVA, this is incorrect, but no worse than what we have already. We can't do better for now because the Type1 kernel interface doesn't tell us what IOVA range the IOMMU actually supports. For the Power "sPAPR TCE" IOMMU, however, we can retrieve the supported IOVA range and validate guest IOVA ranges against it, and this patch does so.

2015-10-05vfio: Remove unneeded union from VFIOContainerDavid Gibson1-13/+3
Currently the VFIOContainer iommu_data field contains a union with different information for different host iommu types. However: * It only actually contains information for the x86-like "Type1" iommu * Because we have a common listener the Type1 fields are actually used on all IOMMU types, including the SPAPR TCE type as well In fact we now have a general structure for the listener which is unlikely to ever need per-iommu-type information, so this patch removes the union. In a similar way we can unify the setup of the vfio memory listener in vfio_connect_container() that is currently split across a switch on iommu type, but is effectively the same in both cases. The iommu_data.release pointer was only needed as a cleanup function which would handle potentially different data in the union. With the union gone, it too can be removed.

2015-10-02target-i386: add ABM to Haswell* and Broadwell* CPU modelsPaolo Bonzini1-1/+21
ABM is only implemented as a single instruction set by AMD; all AMD processors support both instructions or neither. Intel considers POPCNT as part of SSE4.2, and LZCNT as part of BMI1, but Intel also uses AMD's ABM flag to indicate support for both POPCNT and LZCNT. It has to be added to Haswell and Broadwell because Haswell, by adding LZCNT, has completed the ABM. Tested with "qemu-kvm -cpu Haswell-noTSX,enforce" (and also with older machine types) on an Haswell-EP machine.

mapping DIMMs non contiguously allows to workaround virtio bug reported earlier: http://lists.nongnu.org/archive/html/qemu-devel/2015-08/msg00522.html in this case guest kernel doesn't allocate buffers that can cross DIMM boundary keeping each buffer local to a DIMM.

To throttle the guest cpu the caller simply has to call the throttle set function and provide a percentage of throttle time. Signed-off-by: Jason J.

This is a start on using size_t more in qemu-file and friends; it fixes up QEMUFilePutBufferFunc and QEMUFileGetBufferFunc to take size_t lengths and return ssize_t return values (like read(2)) and fixes up all the different implementations of them.
